MACHXNE FOR CUITNG METALLIC RIMS 0R FELLIES.

Application filed. February 13, 1922. Serial No. 536,311.

To all whom t may concern:

Be it known that I, `WILLARD E. RUPE, a citizen of the United States,residing at Sturgis, county of St. Joseph, State of Michigan, haveinvented certain new and useful improvements in Machines for CuttingMetallic Rims or Fellies, of which the following is a specification.

This invention relates to improvements in machines for cutting metallicrims 0r fellies to length.

rlhe objects of the invention are:

First, to provide improved means of cutting metallic fellies from acoiled strip to have them of precisely identical lengths.

Second, to provide such a machine which will eectively cut previouslycoiled channel-shaped fellies. i

Third, to provide improved clamping means for effectively supporting afelly while it is being cut.

Further objects and objects relating to details and economies ofconstruction and operation will definitely appear from the detaileddescription to follow. l accomplish the objects of the invention by thedevices and means described in the following speciication. llheinvention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention isillustrated in the accompanying drawing, forming a part of thisspecification, in which:

Fig. l is a perspectvie View of a punch and press embodying my improvedfelly holding and cutting devices.

Fig. H is ay detail elevation view from the frontvof the machine seen inFig. l, the coil supporting pipe being omitted. The latch lever andsegment are also omitted.

Fig. lll is an enlarged detail elevation view of the punch part and aportion of the coil supporting part of my improved machine with thepunch raised, adjacent coils of the felly material being shown insection.

ln the drawing similar numerals of reference refer to similar partsthroughout the several views.

Considering the numbered parts of the drawing by the numbers, 1 is theframe of a punch press having a reciprocating punch head 2 driven fromthe eccentric 3 actuated from the driving pulley 4. The punch 5 isdouble as indicated at Fig. HI, so that it intersects two portions ofthe felly material at once. Ilhe die block 6 has double depressionscorresponding to the double punch, as clearly seen in Fig. Ill. A

A. pipe 7 is secured to the punch frame by cap screw 8 and extendsparallel to the axis of the coil of felly material and serves as asupport for the said coil 9, as seen in Fig. I. Secured to the punchpress is an annular form 10 of the precise diameter of the tire to beformed, the same being supported in position by a pair of screws 11, 11.The upper side of this form is open at 12, one end abutting the diemember 6, as seen in Fig. Ill. The ends are supported in proper relationby the cross bar 13, seen in Fig. H. Radially projecting guide pins 141are on this ring to guide the end coil of the tire material t0 place.

Curved clamps 15, 15 are pivoted at 16, 16 to bloclr 17 secured to theframe by screw 18 through the transverse slot 18 therein underneath thesaid ring shaped form 10. Levers 19, 19 pivoted at 20, 20 and connectedat 21, 21 to the curved clamp pieces 15 serve to clamp the end coil verystrongly against the annular form. These levers are actuatedsimultaneously by connecting rods 22,22 extending downwardly to rockshaft arms 23, 23 carried on the rock shaft 24 disposed transverselybetween the coil of the material on the lower framework of the machine.rIhis rock shaft is actuated by the latched lever 25 locking to thenotched segments 26. llVhen the end turn of the coil is clamped securelyto position the punch is thrown into gear, clips ofi a small part of themetal from the end of the coil exactly at right angles thereto, and alsocuts olf the end turn of the coil for the felly or rim. The punch isdetailed in Fig. IH. As the succeeding turns of the coil are clamped inprecisely the same way at each operation all the fellies or rims areprecisely the same in size and when butt-welded or otherwise securedtogether constitute perfect, rims or fellies.

The machine is capable of use for fellies or tires of different crosssection, but is especially well adapted to those of channelshape, ashere illustrated, because of thc ease and facility with which the clampscan be litted and adapted thereto, being of round rod as shown.

While I have shown apower punch for use in this connection, it is clearthat a hand operated punch might be made use of, al-

though of course the advantage of the power press would not obtain.

Having thus described my invention What I claim as new and desire tosecure by Letters Patent is: l

l. In a machine for cutting ellies or rims t length from a coil thecombination of a punch press With suitable punching dies, a suitablesupport for the coil, an annular forni at the end thereof secured to thesaid punch press and open at one side with recess for the die portion ofthe said punch, a die portion with double seats side b v side for theopposite ends of the telly or rim, one ot which is close to the end oitthe coil, oppositely disposed curved clamps for em bracing the oppositesides of the said coil to be cut ofi' and forcing the saine into contactwith the said annular forni, a locking lever for controlling the same,and a reciprocating punch disposed to clip the metal at both points inthe die seats, as cescribed.

2. In a machine 'for cutting 'liellies or rims to length from a coil thecombination of a punch press with suitable punching dies, a suitablesupport tor the coil, an annular form at the end thereoic secured to thesaid punch press and open at one side with recess for the die portion otthe said punch, a die portion with double seats side b v side for theopposite ends ot' the telly or rim` one of Which is close to the end ofthe coil, oppositely disposed curved clamps for embracing the oppositesides of the said coil to be cut off and forcing the same into contactWith the said annular form, and a locking lever for controlling` thesame, as described.

recopie 8. In a machine for cutting fellies or rims to length from acoil the combination of a punch press With suitable punching dies, asuitable support for the coil, an annular 'form at the end thereofsecured to the said punch press and open at one side with recess for thedie portion or' the said punch, a die portion with double seats side byside :tor the opposite ends olf the t'elly or rim, one ot Which is closeto the end ot the coil, oppositely disposed curved clamps for ein`bracing the opposite sides et thc said coil to be cut olf and forcingthe same into contact `With the said annular tornin as described.

et. ln a device for cutting 'lellies o to length from a coil, an annulariorm, a clamp means for clamping the coil to the said annular form, adie uith double seat for receiving both ends oit the coil to be cut off,a punch conformed to said seat and adapted to sever both ends or thetelly or rim at the same operation, and suitable sup` ports for the saidpunch and die, as specitied.

5. In a device ttor cutting ifellies or rims to length from a coil, anannular form, a clamp means for clamping the coil to the said annularform, a die with double seat for receiving both ends ot' the coil to becut olif, a punch conformed to said seat and adapted to sever both endsoi the telly or rim at the same operation, and suitable power means 'loractuating the punch, as specified.

In Witness whereof, l have hereunto set my hand and seal.
